Module 7-8-9 Individual Exercise

ACTIVITY DESCRIPTION
Discovering your Site’s Simple Carrying Capacity | Individual Exercise

The Exercise focuses on exploring Parametric RoughCasting of Energy Efficiency, Renewable Energy, Water Efficiency and Rainwater Capture, Food Production, Parking and Land Use using relatively simple, free calculators. 

Each Student must run all calculations. Cohorts can collaborate.

NOTE: Roughcasting is for preliminary (pre-design) planning purposes only. You should not rely on the calculations for accuracy, they are subject to wide range of inaccuracies. However, they are generally better than having no information, and can be valuable for crude test fits.

Upload the weekly Exercise prior to 12:00 Noon on Thursday day of class to your “individual” exercise folder.
Upload a single PDF  / File Size Limit: 20-30 Megs(large files take longer to view  when commenting).

  • Each Student will complete each of the following exercises:
    • Module 7: Stormwater + Land
    • Module 8: Water + Irrigation + Food
    • Module 9: Energy + Mobility
    • Each Student is to assemble a PDF of their work.
    • Use the same format for your sheets as used for your Site Exploration exercise –
      • Include a cover sheet, with your name, track, team number and name, exercise and date.
      • Summary: Include a 1 page summary of the primary outcomes from your calculations.
      • Include snapshots of calculators with your inputs and outcomes.
      • Develop parametric outcomes (graphics not required).
  • Each Project Team: Over the next few weeks, each team will be required to actively integrate the individual Energy+Mobility, Water+Irrigation and Stormwater+Land Tracks into a Whole System solution
